rsplit

%L=RSPLIT(R,S)
% Splits a string S using the regular expression R. Meant to work like
% the PERL split function. Returns a cell array of strings. Requires
% REGEXP.
%
% This function acts a bit like a dual to REGEXP: it returns all of the
% strings that don't match the regular expression instead of those that
% do match. STRREAD is similar to RSPLIT, but it uses a fixed delimiter
% set (whitepace) when use '%s'.
%
%Examples:
% >> rsplit('[_/]+', 'this_is___a_/_string/_//')
% ans =
% 'this' 'is' 'a' 'string'
%
% >> rsplit(',', '$GPGGA,012911.00,7111.04510,N,15841.80861,W')
% ans =
% '$GPGGA' '012911.00' '7111.04510' 'N' '15841.80861' 'W'
%
% >> rsplit(',', '')
% ans =
% {}
%
% >> rsplit(',', ',')
% ans =
% {}
%
% >> rsplit('\s+',' 47.590516667 N 122.341633333 W 1 4 ')
% ans =
% '' '47.590516667' 'N' '122.341633333' 'W' '1' '4'
